Question

ayudaaa necesito la c y la d

Answer 1

Explicación paso a paso:

C)

$\frac{2}{8} + \frac{1}{4} = \frac{1}{2} - z$

$\frac{1}{2} = \frac{1 - 2z}{2}$

$2 = 2 - 4z$

$z = 0$

D)

$m - \frac{1}{7} = \frac{3}{5}$

$\frac{7m - 1}{7} = \frac{3}{5}$

$5(7m - 5) = 7(3)$

$35m - 5= 21$

$35m = 26$

$m = \frac{26}{35}$

Answer 2

Respuesta:

c. 2/8 + 1/4 = 1/2 - z : z = 0

d. m - 1/7 = 3/5

m = 26/35
